Systems and methods of detecting and assigning IP addresses to devices with ARP requests
First Claim
1. A method of discovering and assigning an IP address to a device to be discovered in a communication network having multiple interconnected nodes, the method comprising:
- continuously monitoring, by the device to be discovered, the network for address resolution protocol (ARP) requests;
transmitting, by the discoverer node to the network, a plurality of ARP requests associated with a selected first IP address;
receiving, by the device to be discovered, the plurality of ARP requests;
determining, by the device to be discovered, whether the plurality of ARP requests are unanswered by other devices in the network;
answering, by the device to be discovered, the plurality of ARP Requests with an ARP reply to claim the selected first IP address associated with the plurality of ARP Requests; and
exchanging a pair of User Datagram Protocol (UDP) packets between the discoverer node and the device to be discovered.

Abstract
A method of discovering and assigning an IP address to a device to be discovered in a communication network having multiple interconnected nodes includes continuously monitoring, by the device to be discovered, the network for address resolution protocol (ARP) requests. The discoverer node transmits a number of ARP request to the network. The device to be discovered receives the number of ARP requests. The device to be discovered determines whether the number of ARP requests are unanswered by other devices in the network. The device to be discovered answers to the number of ARP requests with an ARP reply to claim an IP address associated with the number of ARP requests. The discoverer node and the device to be discovered exchange a pair of User Datagram Protocol (UDP) packets to complete the detection process.

20. A system for discovering and assigning an IP address to a device to be discovered in a communication network having multiple interconnected nodes, the system comprising:
-
a discoverer node coupled to a first processor to transmit a plurality of Address Resolution Protocol (ARP) requests associated with a selected IP address to the network; and the device to be discovered coupled to a second processor, wherein the device to be discovered continuously monitors the network for ARP requests, receives the plurality of ARP requests from the discoverer node and determines whether the plurality of ARP requests are unanswered by other devices in the network; wherein the device to be discovered answers the plurality of ARP requests with an ARP reply to claim the selected IP address associated with the number of ARP requests and wherein the discoverer node and the device to be discovered exchange a pair of User Datagram Protocol (UDP) packets.
